Arduino senses the environment by receiving inputs from add-on devices such as sensors, and can control the world around it by adjusting lights, motors, and other actuators. In this class you will learn how and when to use the different types of sensors and how to connect them to the Arduino. Since the external world uses continuous or analog signals and the hardware is digital you will learn how these signals are converted back-and-forth and how this must be considered as you program your device. You'll also learn about the use of Arduino-specific shields and the shields software libraries to interface with the real world. Please note that this course does not include discussion forums.

Module 4

In this module we’ll examine Arduino shields and how they are used to extend the capabilities of an Arduino-based system. Shields are printed circuit boards that are stacked on top of the Arduino together with libraries that enable the new hardware to be used through an Arduino sketch. We’ll describe the benefits of shields and their basic construction as well as the use of libraries in interfacing with each shield.
This module also describes how to connect your IoT device to the Internet using shields. We focus on an Ethernet shield in order to establish a wired network connection, and a WiFi shield to establish a wireless connection.
